Yes, I remember a source comment to that effect. But whatever the buffer
policy, read-block 'immediate won't (always) do since it may fail to
deliver any byte. (I didn't look up the port-handler, but I assume it
gives up on a locking device if asked for 'immediate bytes. This would
fit the description in ports.scm or somewhere.) That is, r.s.p wouldn't
implement the conditional forward-progress guarantee of the spec.
